You’ve not bothered citing them. You’ve cited everything else but Lumen Gentium. Why is this? Is it because Lumen Gentium shows that you are wrong?
Again, you are free to believe what you want, but you are not free to teach whatever you like about the Catholic church.
So, let me get this right....
The CCC and the ex cathedra proclamations of the past popes to not really mean what they said?
IOW, when the pope was infallibly speaking on there being no salvation outside the Catholic church, then it wasn’t really infallible? Or what?
Tell me how two contradictory things can be true at the same time.
